createScalarFunction UDF with Utf8 return type not working as expected

[Raviston6296]

What happens?

Scalar udf not working as expected for return type Utf8

To Reproduce

Basically create a UDF that returns the exact value. The results will all turn into \u0000

// Function to append 'data' to the input string
function stringTest(a) {
  try {
    return a + "hello";
  }catch(ex){
    console.log(ex)
  }
}

conn.createScalarFunction('stringTest', new Utf8(), stringTest);
